“When a liquid like hand sanitizer reaches a ‘flashpoint’ it can produce vapors which could ignite—but all those vapors nevertheless require to be met with an ignition resource to catch fireplace,” he explains.
This flashpoint is 63 degrees F, adds Jack Caravanos, DrPH, clinical professor, NYU’s Faculty of World-wide Public Wellness, New York City. “If you place this gel in a shallow cup and the temperature of the alcoholic beverages gel and space air was 63 degrees F and previously mentioned, then lights a match a bit over the liquid would lead to it to flame up,” he suggests.
